As the San Antonio Spurs gear up for a high-stakes 2026–27 campaign, all eyes are locked on their ascending young core. Following a hard-fought run to the Western Conference Finals, the expectations in Texas have skyrocketed. But if guard Stephon Castle wants to make the massive individual leap into bona fide stardom this season, he has one glaring obstacle he must overcome: his turnover woes.
While much of the external chatter surrounding Castle has focused on his shooting progression, insiders and analysts know that ball security is actually the single biggest area holding him back.
The Costly Turnovers Threatening the Spurs’ Ceiling
Castle’s playmaking brilliance is undeniable. Last season, he led the Spurs in assists by averaging an impressive 7.4 dimes per game. However, his baptism by fire as the primary point guard early in the year resulted in some unsightly ball-security numbers, leading the entire NBA in turnovers through the first 20 games.
While veteran guard De’Aaron Fox stepped in to help rein in those mistakes during the regular season, the problem unfortunately resurfaced on the game’s biggest stage. When Fox missed the first two games of the Western Conference Finals against the Oklahoma City Thunder, Castle was thrust back into the primary distributor role—resulting in a staggering 20 turnovers across that stretch.
Analysts point out that those costly miscues directly influenced the tight margins of Games 1 and 2. With cleaner decision-making, the Spurs might have stolen a win in regulation during the opener and avoided running out of gas in Game 2.
The Solution: Playbook Mastery and Shared Duties
Fortunately, Castle’s turnover struggles are entirely correctable. Much of last season served as his de facto rookie year adjusting to high-usage playmaking responsibilities. By simplifying his reads, tightening up risky passes, and gaining deeper mastery of the playbook, his numbers should naturally stabilize.
Furthermore, a tactical adjustment from the coaching staff could instantly ease the burden. When Castle and Fox shared the floor and split playmaking duties last season, Castle’s turnovers plummeted.
While Fox struggled at times playing off-ball due to his perimeter shooting limitations, finding a better offensive balance between the two guards could unlock everything. Castle is at his absolute best when running pick-and-rolls, tossing lethal lobs to Victor Wembanyama and Luke Kornet, or finding shooters stationed on the perimeter.
The Road Ahead
If San Antonio can effectively distribute ball-handling duties and Castle minimizes high-risk passes, the results will speak for themselves. Retaining his elite assist numbers while slashing his turnover rate—paired with his steadily improving jumper—will transform Castle from a promising young talent into an undeniable star.
If he checks this final box, the Spurs’ championship aspirations will become very real.
Do you think Stephon Castle can cut down his turnovers and emerge as an All-Star caliber guard this season, or should the Spurs rely more heavily on De’Aaron Fox to run the offense?
